Recipes

Fermented Cherry Tomatoes

• Cherry Tomatoes (should be hard, not mushy), enough to fill quart mason jar
• Fresh springs of either parsley or basil, or both
• 2 Garlic cloves, peeled and chopped
• 2 pinches of whole black peppercorns
• 4 Tsp unrefined salt
• 2 cups filtered water
• 1 quart mason jar

Instructions

• Place peppercorns in bottom of jar, then layer in tomatoes, herbs and garlic
• Make brine in a separate container by dissolving salt in water. Once mixed, pour over tomatoes, but keep 1 1/2 inch headspace.
• Place fermented weight on top to keep tomatoes under the brine
• Place fermentation lid or regular lid on the jar and ferment at room temperature, away from direct sunlight, for 10-14 days
• If using a regular jar lid, unscrew daily to release built up fermentation gasses and avoid overflow
• When ready, should taste a bit tangy with a slight fizz
• Remove weight, add a regular jar lid and place in cold storage (refrigerator or root cellar)
• Ferment should last several months
• Use as a snack, mix into salads or eat as a side dish

Tomato Paste

• 10 lbs very ripe tomatoes, cored
• 1 to 4 tbps kosher salt, to taste
• 1 tbsp extra-virgin olive oil (to grease baking sheet and more to top off the jar)

Instructions

• Halve or quarter tomatoes. Remove the seeds with your fingers.
• Place all tomatoes in an 8-quart stainless steel pot and bring to a boil, stirring occasionally, until the tomatoes release their juices. Boil briskly for 30 minutes until the tomatoes soften and the juices reduce.
• Pass the tomatoes through a food mill fitted with a fine disk to remove the skins and any remaining seeds.
• Return the tomato purée to the same pot and place it over high heat. Stir in the salt, reduce the heat to medium and simmer, stirring frequently, until the purée has reduced to about 1 quart (4 cups), approximately 45 to 55 minutes. Turn down the heat as the purée thickens to prevent it from bubbling and splattering.
• Lightly grease a 12-by-17-inch rimmed nonaluminum baking sheet with oil. Use a spatula to spread the thick tomato purée in an even layer. It should cover the entire baking sheet.
• Preheat the oven to 200ºF (93ºC) and turn on the convection fan if you have one. Position a rack in the center.
• Place the baking sheet in the oven and bake for 30 minutes.
• Remove from the heat (but keep the oven on) and stir the purée with the spatula so that it dries evenly and doesn’t form a crust.
• Re-spread the purée with the spatula into an even rectangle about 1/8 inch thick. If any part is too thin, it may burn. Because of evaporation, the purée will no longer cover the baking sheet. With a paper towel, remove any bits of tomato that cling to the edges or exposed bottom of the baking sheet as these will burn onto the baking sheet.
• Return the baking sheet to the oven and continue baking until the tomato purée is no longer sauce-like but very thick, stiff, and a little sticky, about 3 more hours. Every 20 minutes, stir and carefully re-spread the purée as before. The rectangle will become progressively smaller as the remaining water evaporates. Taste and, if desired, add more salt.
• Once done, let the tomato paste cool to room temperature.
• Use a spoon and move the paste to a clean jar, tamping it down to make sure there are no air pockets. Level the surface with the back of the spoon. Cover the surface completely with olive oil so that the paste isn’t exposed. Screw the lid on the jar and refrigerate. It will keep in the refrigerator for at least a year.
• When using in dishes, always salt the dish after you’ve added the tomato paste as it will bring a lot of concentrated saltiness.
• After each use, level the paste surface and top with more oil to keep the remaining tomato paste completely submerged.
